Application tiled May 5, 3 5563. Serial l'l'o, dfiWEf To all whom it may concern:

lilo it known that it, Airmen E, a citizen of the United States, resin-lug; Charleston, in the county ofl lanawha and State of West Virginia, have invented certain new and useful Improvements in Dust Preventive Attachments, for Coal-Cutting Machines; and I do hereby-declare the fol lowing to be a full, clear, and exact descrip tion of the invention, such as willcnalile others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in mining machines and has relation more particularly to an attachment therefor for preventi dust.

it is an object of the invention to provide a novel device of this character wherein a spray of water is directed upon the coal being cut.

in the cutting of coal, the dust at the face becomes a thick cloud forty to fifty feet back from the coal. and is by the air currents car ried all. through the mine depositing itself in' the roadways and is the greatest factor of danger in. any mine when an explosion of occurs, for it is then blown about by the force of the explosion and ignites i1nrnediately, which proves a menace to life and property.

lit is an object of the invention to obviate this disadvantage.

It is an ohject of the invention to provide a novel device of this character wherein the sprayingjets travel into the cuts with the blades or cutting; instrument.

it also an object ot the inventimi :Z'UV'ltlti a novel device oi this cu tion oi the machine, said motor also ing; the pol p for ejecting the N lit also an object of the iuvenli' novel device of this chit;

which will he sin'iple in ct t and 1d an'tugg cmis in practice and computativelyinexpensive to manufacture.

The endless chain 3 is mounted. one frame 4., which is adapted to he moved forwardly as the cut is made, Mounted on the movable frame 4, is motor 5 for operating the endless chain This motor may he as desired, may any oil the other features before enumerated.

Suit-aloly attached to the movable frame, preferably beneath the motor 5, is a pump,

The pump cylinder 6v has an induction port 11 in communication with s'tlexi'ole pipe 12, which leads to a suitable Water source, which in this instance is shown as'a portable tank 13. The pump cylinder is also provided with an education port 14%;, which in CUIIlilitlllitYi" 011 with pipe 15 lined the it n it ,2! machine, pretl pc is not necessary to ion of the invention, it
